The first fuel cells were invented in 1838 but they were not used commercially until the NASA space program developed a program using fuel cells to generate power for satellites and space capsules. Discover in this article how the MASS-VIEW® can be used to create a fuel cell. ...
What is a Fuel Cell? Fuel cells generate electricity through an electrochemical reaction rather than combustion. Inside a fuel cell, hydrogen and oxygen are combined to generate heat, water and electricity. They represent a clean, efficient, dependable, and quiet source of power that does not need to be recharged, but can continue to produce electricity as long as fuel is ...
We used DEMS to investigate the mechanism of carbon support corrosion (CSC) in-situ at the cathode of proton exchange membrane fuel cell (PEMFC). The cathode exhaust gases were sampled with a Hiden Analytical QIC-20 mass spectrometer. The spectra of gases were correlated in our laboratory for the first time to characterize most reactions that happen at the ...
But in many MECs, platinum is often used as catalyst, which limits the practical applications of MECs. To reduce the cost of the MECs, Ni-based alloy cathodes were developed by electrodepositing. In this paper hydrogen production using Ni-W-P cathode was studied for the first time in a single-chamber membrane-free MEC. ...
The electrocatalytic activity of bare and 2-ethyl anthraquinone-modified graphite felt (2-EAQ/GF) toward oxygen reduction was investigated using a cyclic voltammetry technique in a neutral solution. The prepared cathodes were tested for electrogeneration of H2O2 and electro-Fenton oxidation (EFO) treatment of neutral coking wastewater (CW) after biological process, using a ...
Using a self-made Pd/C gas-diffusion electrode as the cathode and a Ti/IrO2/RuO2 anode, the degradation of 4-chlorophenol has been investigated in an undivided electrolysis device by the electrochemical oxidation processes. ...
Oxygen has been so far addressed as the most preferable terminal electron acceptor in the cathodes of microbial fuel cells (MFCs). However, to reduce the oxygen reduction overpotential at the cathode surface, eco-unfriendly and costly catalysts have been commonly employed. Here, we pursued the possibility of using a high surface area electrode to ...
Using Pt0.5Pd0.5 (40 wt% on Vulcan XC-72) as a catalyst at the anodic side of a fuel cell, a typical cell voltage of 0.7 V was obtained at a current density of ca. 1.1 A cm−2. Using Pd (40 wt% on Vulcan XC-72) as a catalyst at the cathodic side of an electrolysis cell, a typical voltage of 1.70 V was obtained at a current density of 1 A cm−2. ...
